After the departure of students and some teachers remained on station in
Petunia 11 workers to join them yet geomorfolog Mark Cross. The weather has
changed. Due to the strong north winds and high waves, which are particularly
disturbing traffic on the site, catching fish and diving, to the south moved
masses of sea ice. Pack ice to get into the fjord and with them the animals
appeared to sea ice-bound. We are particularly pleased walruses (Fig. 1), who
sometimes show up in front of the station.

On the contrary, pleased us that the sea ice was brought and polar bears,
especially after the arrival of our satellite phone reports that about 40 km
from our station polar bear killed seventeen Brit. Do not know if we are to
believe the German tourist guides, who tell us that in the same area moves about
10 other bears. We had to proceed to further tighten security measures and work
in the field and we need to plan according to weapons at our disposal. The
decision to change locations algologických taking of samples, which we started
after reports of sea ice proved to be prudent: incident happened just in the
places where we were originally headed.

John Kvíderová measured daily course of photosynthesis in green algae
Zygnema of wetlands on the coast (Fig. 2) using a handheld fluorometer (Fig. 3).
Before returning still performs regularly measuring photosynthetic activity and
nitrogen fixation for long-term experiment in open glass in kopečkovité tundra
and take samples of water in wetlands with a dominant cyanobacteria Fellowship,
supplemented by measurements nitrogenázové activity to determine the nitrogen
balance

Otakar Strunecká (Fig. 4) continued collecting, classification and
cultivation of filamentous cyanobacteria from a single area Dicksonfjorden.
Because the pH of water in Petuniabukta is usually higher than 8.5, trying to
find streams with lower pH in the Paleozoic sandstones in the middle of Dickson
Land. Special attention to soil krustám that cover large parts of river deltas
and Nathorstelva gradient expansion of cyanobacteria in alpine stream Kulmelva
(Fig. 5).

Botanical-paleoecological section is focused on taking deposits from the
lakes created on marine terraces around holocenního old station – on the
young terrace near kopečkovité tundra in the estuary and around Brucebyenu
Ebby. The subsequent analysis attempts to reconstruct the environmental
conditions that prevailed at the time of their creation through various proxy
analysis (eg chemical analysis, pollen, plant macro-remains and invertebrates).
Analysis of the droppings of reindeer and ptarmigan collected in a transect from
freshly odledněných advanced to the tundra to try to find out whether these
animals may facilitate the dispersion of seeds of some plants and facilitate
colonization of the foreground of the glaciers.

Zoological and parasitological group worked in the sea, in freshwater and on
land. Devetter Miloslav and Karel Janko watched and soil micro mesofaunu (Fig.
7) on the ecological gradient in odledněném territory before facing glaciers
and changes in soil microfauna on the vertical gradient of altitude. Also
investigated the recovery of freshwater lakes (Fig. 8) and trophic relationships
between Diffuser, daphnia and listonoh.

This group also strengthened ornithologist Vaclav Pavel (Fig. 9). Came
rekognoskovat terrain and plans for the future research Tern Sterna paradisea
(Fig. 10) and compare them with populations of Sterna vittata Antarctic.

Parazitologové (Oleg.Ditrich, Tomas Tyml, Alena Kodádková, Figs 11 and
12) continued to study life cycles of parasites of fish and marine
invertebrates. Investigated the effect of parasites on the fitness of fish and
use new equipment and documentation station microscopic technique to capture
images of living parasites, such as myxosporeí (Fig. 13) or a parasitic ciliate
(Fig. 14).

Mark Cross (Fig. 15) carried out the structural classification of soils in
the vicinity of the station. Into selected sorted polygons installed sensors.
These measurements are compared with their equivalents in Central Europe.
Glacial sediment samples went to the micromorphological analysis of quartz
grains.

Jan Kavan continues the measurement of hydrological characteristics of the
selected model basin, including monitoring of lakes. (Fig. 16). In a short time
remains on the station with Jane and her work Kvíderová write in more detail
in the next report.
